A workspace is a logical work area that enables multiple users to work within the same Oracle APEX installation while keeping their objects, data, and applications private. Creating and managing an APEX workspace involves the following statements:

• During workspace creation, you can associate the workspace with an existing database schema or create a new schema for the workspace. A schema is a collection of database objects such as tables, views, indexes, etc. that belong to a user.
• A workspace enables multiple users to work within the same Oracle APEX installation. Each user can have a different role and privilege in the workspace, such as workspace administrator, developer, or end user.
• A workspace can be associated with one or more schemas. You can add or remove schemas from a workspace after it is created.
• You can create as many workspaces as you need in an APEX Service (APEX Application Development) instance. There is no limit on the number of workspaces per instance.

Universal Theme has many features that make it an ideal user interface for Oracle APEX applications. Three of the key features of Universal Theme are:

• Versatile UI Components: Universal Theme provides a rich set of UI components that can be used to create interactive and engaging applications. Some of the UI components include cards, lists, charts, calendars, maps, timelines, accordions, tabs, modals, alerts, and more.
• Responsive Design: Universal Theme adapts to different screen sizes and devices using CSS media queries and grid layout. It ensures that the applications look good and work well on any device, from desktops to tablets to smartphones.
• Easy Customization: Universal Theme allows developers to customize the appearance and behavior of their applications using template options and theme styles. Template options enable developers to apply different styles to components on a page without writing custom code. Theme styles enable developers to change the overall look and feel of the application by choosing from a variety of pre-built styles or creating their own.

You can access the Shared Components page from two places in App Builder: the Page Designer and the Application home page. In Page Designer, you can click on the Shared Components icon at the top of the page to open the Shared Components page in a new tab5. In the Application home page, you can click on the Shared Components link in the center of the page to navigate to the Shared Components page6. Gallery, SQL Workshop, and other pages do not have direct links to the Shared Components page.

A calendar is a type of component that enables users to view and manage data based on dates. A calendar can display data in different views, such as monthly, weekly, daily, or list. Users can also interact with the calendar by creating, editing, or deleting events, or by using drag and drop functionality. Three of the features of a calendar in Oracle APEX are:

• Next - Navigates to the next month. This feature allows users to move forward in time and see the events for the following month.
• Previous - Navigates to the previous month. This feature allows users to move backward in time and see the events for the previous month.
• Month, Week, Day - Displays a monthly, weekly and daily view. These features allow users to switch between different views of the calendar and see the events for a specific month, week, or day.

When you click a Customer Name in the Customers report, the Customer Details form dialog page is displayed. This involves two events: page rendering and page processing. Page rendering is the event that occurs when APEX generates and sends the page to the browser. Page processing is the event that occurs when APEX receives and processes the page from the browser. In this scenario, both events happen because the Customer Details form dialog page is a modal dialog that uses AJAX to communicate with the server without reloading the entire page. Page compilation is not an event, but an action that occurs when APEX compiles an application or a page before running it. 

A Page Computation can be created from two tabs in Page Designer: Rendering Tree and Processing. In the Rendering Tree tab, you can create a Pre-Rendering Computation or a Post-Rendering Computation by right-clicking on these nodes under your page node. In the Processing tab, you can create an After Submit Computation by right-clicking on this node under your page node. Dynamic Actions and Shared Components are not tabs in Page Designer, but sections in Application Builder where you can create other types of components for your application

A faceted search page is a type of page that allows end users to filter data by applying one or more facets. A facet is a set of filters based on a column or expression. By default, when end users select a facet value, they need to click on an Apply button for that facet to apply the filter to the report. To make report filtering automatically executed when any facet value changes, you need to navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute. The Batch Facet Changes attribute determines whether end users need to click on an Apply button for each facet or not. When this attribute is disabled, the report is automatically refreshed when any facet value changes. The other options are not relevant to the report filtering behavior.

A map is a type of component that enables you to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST Data Source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Two of the statements that are true about maps in Oracle APEX are:

• Background maps do not require any API keys. This statement is true because Oracle APEX provides several background map options that do not require any API keys or registration to use. These options include OpenStreetMap, Stamen Maps, CartoDB Maps, and Esri Maps.
• Maps support REST Enabled SQL. This statement is true because Oracle APEX allows you to use REST Enabled SQL as a data source for your map regions. REST Enabled SQL is a feature of Oracle REST Data Services (ORDS) that enables you to execute SQL statements and PL/SQL blocks over HTTPS using REST endpoints.

The Access Control feature pages are a set of pages that allow developers to implement role-based access control for an application. The Access Control feature pages consist of four pages: Administration, Users, Roles, and Role Assignments. The Administration page allows administrators to perform various tasks related to managing users and roles, such as:

• Add Users: Administrators can add new users to the application by entering their username, email address, password, status, etc.
• Assign roles to users: Administrators can assign one or more roles to users by selecting them from a list of available roles.
• Edit Users: Administrators can edit user details such as username, email address, password, status, etc.
• Delete Users: Administrators can delete users from the application by selecting them from a list of existing users.
• Lock/Unlock Users: Administrators can lock or unlock users by changing their status from active to locked or vice versa. You cannot create authorization schemes or create new application roles using the Administration page. You can create authorization schemes by using Shared Components > Security > Authorization Schemes. You can create new application roles by using Shared Components > Security > Access Control > Roles.

To hide a few columns in your interactive report, you should choose Columns from the Actions menu. This option allows you to select which columns to show or hide in your report by using checkboxes. You can also reorder or resize the columns from this option.

The other options are incorrect because:

• Filter allows you to filter the data in your report by applying one or more conditions on the columns.
• Data allows you to add, modify, or delete data in your report by using inline editing or modal dialog editing.
• Format allows you to change the appearance of your report by applying conditional formatting rules or highlighting colors.
